Browning AK49H Sheave
The Browning AK49H Sheave is a high-performance single groove cast iron sheave designed specifically for fractional horsepower (FHP) applications and light-duty power transmission. Engineered for versatility, this 4.75" outside diameter V-belt pulley is precision-machined from close-grain cast iron, ensuring maximum durability and tight tolerances that prevent premature belt wear. To guarantee smooth, vibration-free operation in demanding HVACR environments, each unit is statically balanced prior to shipping.
This fixed pitch sheave is designed for use with a split taper H-series bushing, providing a more secure, 360-degree clamp on the shaft compared to standard set-screw pulleys. It is fully compatible with 3L, 4L, and A belt sections, offering flexible power transmission options. With a datum diameter of 4.5" for A belts and a 4.16" pitch diameter for 3L belts, the AK49H ensures consistent RPM transfer for blower motors and fans. Its robust construction allows it to handle the radial loads typically found in commercial air handlers and condenser fan assemblies.
Key Benefits- Precision Machined: Constructed from high-quality cast iron for superior concentricity and heat dissipation.
- Vibration Reduction: Statically balanced design extends the life of motor bearings and reduces system noise.
- Interchangeable Bushing System: Utilizes H-series bushings to accommodate various shaft diameters from 3/8" to 1-1/2".
- Belt Versatility: Single groove geometry supports A, 4L, and 3L V-belts for broad application compatibility.
What is the difference between AK and AKH sheaves?
Standard AK sheaves typically use a fixed bore with a set screw. The AK49H is part of the AKH series, meaning it requires a separate H-series split taper bushing for installation, providing a superior grip on the motor shaft.
Can I use a B-section belt with this sheave?
No, the AK49H is specifically grooved for A (4L) and 3L belts. Using a B-section belt will result in improper seating, leading to significant slippage and potential drive failure.
Does the AK49H come with the shaft bushing?
The H-series bushing is sold separately. This allows you to select the specific bore size required for your motor shaft while using the same 4.75" sheave.
